Dear fellow proffesionals once again I find myself still asking questios about
MSA with respect to uncertainties.

Someone has suggested that per ISO 17025 uncertainties need to be measured between calibration and GR&R. I can not seem to find such a statement anywhere with in the standard.

Currently all calibrations are out sourced and uncertainties are included on
all certifications.

Can anyone shed some light.

As always, I thank you in advance for your help and expertise.

Cpine :bonk:

If your calibrations are outsourced to an accredited lab and uncertainties are reported, you have the information you need for that instrument.

Now feed the uncertainties into your R&R. Remember it is reported as an expanded uncertainty (95% confidence), so you may well have to divide by two to reduce to standard uncertainties (67% confidence).

Hope this helps.
